The courts, the medical profession and the public have shown indications of a decided dissatisfaction with existing methods of determining criminal responsibility. This will certainly continue as long as the sole test of competency is the power of the accused to discriminate between a knowledge of right and wrong at the time when the act is committed. The conditions which lead to crime have been made the subject of scientific study by many. One of the early investigators in this field was Morel, who saw in the criminal a personification "of the various degenerations of the species." Much has been said of "moral insanity," a condition referred to by Abercromby as one "in which all the upright sentiments are eliminated while the intelligence presents no disorders." Lombroso advanced the theory that criminality is a form of atavism—a reversion of man to the primitive and savage type represented by his early ancestors. This theory was based on a careful study of the anatomical, physiological and psychological characteristics of primitive man. His classification included the occasional, the emotional, the born criminal, the moral insane, and the masked epileptic. Marro offered an anatomical basis for the degenerative theory in the form of nutritional defects in the central nervous system. Ferri distinguished between criminal lunatics and emotional criminals and held crime to be "a phenomenon of complex origin and the result of biological, physical and social conditions." "Habitual criminals," he says, "are the victims of a clear, evident and common mental alienation which causes the criminal activity," while the occasional offenders are to be explained by "the impulse of opportunities more than the innate tendency that determines the crime." The emotional criminal, according to Ferri, is a sane and moral individual overcome by momentary emotional paroxysms referred to as a "psychologic storm." Garofalo, on the other hand, looked upon crime as "an offense against the fundamental altruistic sentiments of pity and probity." From his point of view a criminal act was an indication of the loss of a proper sense of appreciation of the life or property of another—a moral anomaly. The Italian school of criminology was responsible also for the theory that criminal acts are only the expression of epileptic symptoms. Sociological workers have attributed crime to influences which overcome the natural resistance of the individual, a variation from which is merely an inability of the person to conform to the laws of environment. Max Nordau sees in human failings only an abnormality which he describes as "human parasitism." Others look upon crime as the natural product of a modern social and economic system. Colajanni ascribes alcoholism, vagrancy and prostitution to poverty, but crime, he says, is "due to necessity and to the degree and kind of education received." In the light of our present knowledge the conclusion would appear to be warranted that
